I have begun to notice that I have been seeing too many suggestions in my intellisense. For example, I have a table "dbo.Committees" (which yields an alias of "c"), a view called "dbo.CurrentCommittees" (which yields an alias of "cc"), and finally a view called "dbo.CurrentCommitteesEntityTypes" (which yields an alias of "ccet"). So far, all as expected.

I'm looking into this now, but I don't think I'm seeing the same suggestions you are. I've created the table and views you mentioned and in the first example I just get suggestions from ".cc":
Can you think of anything else that I might need to do to recreate this?

One option that might also affect this is under Options->Suggestions->Behavior->Types of suggestions->"List all database columns after a SELECT statement" - so just double check to make sure that is unticked.

It looks like it suggests aliases if they have been typed exactly. I think this is a knock on from our fixes for aliases not being resolved correctly if there are script errors between their use and definition (which is pretty common if you're still typing the script). I'll have a look into what we can do about a fix.

Edit: Just a quick update on this, we think we've got a fix however it needs a bit of restructuring on how we calculate the suggestions if we want to keep our previous fixes. We should hopefully have something out in the beta next week - I'll let you know when it's up.
